Refactored logClientSend in libCom/logClient/logClient.c; took the code between the mutex operations and
moved it to a private method - sendLogMessageinChunks. Call this method once for the prefix (if it exists) and once
for the actual message.
Added ioCsh registration code into src/libCom/iocsh/libComRegister.c registering a command called
"iocLogPrefix" that sets this prefix.
Unit tested with and without prefixes.
Performance tested with and without prefixes - without prefix is approx the same. With prefix is about
twice the time (reflecting the two calls to sendLogMessageinChunks I think)
replaced the osdSysTime provider with a new osiClockTime provider,
stringin device support puts record into alarm if no working provider,
added osdTimeRegister() to RTEMS/osdTime.h.
* Added new monitoring API with insert and remove callbacks; the old API is
still supported though.
* Added report routine, callable from iocsh.
* taskwdInsert() can take a NULL tid, meaning the calling thread.
